3. Device Debugging

3.1 Device Connection

Device connection could be divided into three parts: power connection, signal

connection and control connection (used for software debugging).

Power connection: device power supply. Connection method: connect power

cord to power plug.

Signal connection: the method transferring signal from signal source to LED

large screen. Connection method:

signal source→(e.g.: computer)Splicing Processor→Sending card→Large

screen.

Control connection: connect computer with device control port and debug device

connection method. There are three connection methods:

（1）Connect 100 mbit network control port with splicer LAN1 port, which can

set device software.

（2）Connect computer gigabit network port with splicer LAN2 port, which can

not only set device but also echo signal source image.

（3）Connect one crystal head of serial port line which is randomly donated by

device with splicer COM port, and plug DB9 into computer serial port. Any of the

three methods realizes device software control.

3.2 Debugging Procedure

Step 1: Click “MENU” to enter into main menu interface and click “Device

Mode” to select splicing mode: copy mode, horizontal mosaic, and vertical mosaic.

Note: Copy Mode: all output contents are consistent; horizontal mosaic: contents

of all outputs are arranged horizontally; vertical mosaic: contents of all outputs are

arranged vertically;

Step 2: select suitable splicing mode and click “OK”; get back to main menu

interface to select “Screen parameter” and enter into its setting interface. Set loaded

screen point of each output interface and click “Confirm” after inputting, and then

screen splice is finished.

Note: there are two ways for number input:

(1)Adjust by rotate knob. Step length can be adjusted by “×1”“×10”“×100”, for

instance, “×100”means that number of rotate knob increases by 100 each time.

Step 3: get back to main menu interface to select “Image layout” and enter into

image number selecting interface to select image number required to be set.

Note: In case of signal image, skip this step. For multi-image, it’s OK if image

number and item requirements are in consistent. Following operations can be taken

when layouts are not consistent.

Step 4: Click “OK” and return to main menu interface; select “Image parameter”

and enter into its setting interface to set size and position of each image.

Step 5: Click “Menu” and return to main menu interface; select “Clipped view”

to enter into its setting interface to set size and position of each image.

Note: This step should be skipped if full display of signal source is required on

large screen; while if certain signal source of multi-image is needed to be extracted,

only setting of signal source image is required; if horizontal size or vertical size is 0, it

means no local extraction is required in this direction.

Step 6: Click “MENU” and return to main menu interface; select “Save setting”

to enter into Data storage interface; select any mode and click “OK” to save data.

Note: Mode 1 is default startup data of device boot; it’s suggested that the most

common mode or that required by device boot should be saved to Mode 1.

At this point, basic device debugging is completed. If there is other requirement,

repeat the operation and save it as other mode.

After device debugging, just call saved data according to different condition

requirements in later stage.

Data call is divided into forms:

is convenient when mode scenario is few.

(2) For User mode call of Main Menu, click “MENU” and select “User Mode” to

enter into its extraction interface. Then select desired mode and click “OK”.

3.3 Case explanation

Device debugging steps are explained by following cases.

Case 1: screen size is 2112×896 and loading transmitting card is shown as picture

below:

Requirement: whole computer desktop should be displayed completely.

Debugging Procedure:

Step 1: click “MENU” and enter into main menu interface to select “Horizontal

mosaic” of the first item “Device mode”.

Note: as two transmitting cards are in the 1x2 arrangement, horizontal mosaics

are needed then.

Step 2: Click “OK” to return to main menu interface; select “Large screen

parameters” to set size of each output interface.

Note: Input according to corresponding transmitting card size of each output

interface. For OUT1, its horizontal size is 960 and vertical size 896; for OUT2, they

are 1216 and 896 respectively.

Step 3: After inputting, select “Confirm” and return to main menu interface. The

large screen splicing is finished, select signal source needed to display on screen and

click corresponding key. E.g.: for display of computer signal on large screen and

connection of computer DVI interface with “S1-DVI” port of the back device, just

click “S1” in the front which means choosing the signal to display on the screen.

Step 4: After selecting signal and normal display of large screen, save all setting

data. Click “MENU” to enter into main menu interface, and then get into “Save

setting” interface to select “Mode 1” and click “OK”. Things will be fine when it

suggests saving successfully.

Note: Mode 1 is default startup data of device boot; it’s suggested that the most

common mode should be saved to Mode 1 and the device can save 32 kinds of modes

at most.

Case 2: Screen size is 1792×1344 and loaded transmitting card is shown as

picture below:

Requirement: 1) Whole computer desktop should be displayed completely.

2) Screen is divided into three parts with proportion of 1:2:1.
